The Production Plan is a list of parts that you plan to sell, or otherwise need, in addition to other demand placed on MRP such as Sales Orders or Quotations. Production Plan quantities are, in effect, artificial Sales Orders.

WARNING: You MUST NOT think of Production Plan items as the quantity of parts that will be manufactured in production. There is no direct relationship to Production Plan quantities and the manufacturing recommendations of MRP. MRP will view, if the option is chosen, Production Plan quantities as direct demand like Sales Orders and will use normal algorithms to assess the need to manufacture the part and in what quantity and on which date.

TIP: Setting a Production Plan for a part is useful where you do not have a Sales Order lead time sufficiently long for proper scheduling of lower level items. You can use the plan to artificially load direct demand on MRP for the future, when it is unlikely that Sales Orders will cover a realistic level of factory output.

TIP: There is a very useful system preference which can automatically adjust the production plan to take account of dispatches. For details see the System Preferences window Sales Orders tab pane.

The post MRP Planning, Processing and Results: Production Plan Maintenance                                                                                       appeared first on Caliach.

The reason a Phantom part can (correctly) show up in the MRP results is because a component part inside the Bills of Material has the ‘For suppliers of the part MRP will order PO kits’ checkbox ticked (see red arrow).

Be aware that to place a tick in the checkbox you can click your left mouse anywhere within the yellow box, seen in the image. It has happened before that someone accidentally clicked this area when creating a part then duplicated more parts after the fact creating a confusing situation.

To further explain what this is for we have created a top level assembly part number (TTLA-1) and created a Production Plan demand for 100x pieces (see image near right).

Within the part number TTLA-1 is a Phantom Part Number (TPA-1)
The Phantom Assembly has 5x components within (TC-1 to TC-5). (see second image below for TTLA-1 Bills of Material).

In this demonstration component ‘TC-1’ is the only part with the checkbox ‘For suppliers of the part MRP will order PO kits’ ticked.

With the above scenario set, we run MRP and as you can see the in the image below the results are asking to buy 100x of (Phantom) part number TPA-1 and no component parts.

This is in fact correct as what you are telling the system is that the only way to buy component part number TC-1 is to buy the Phantom part number TPA-1 from a supplier.

In this case when stores come to receive a Phantom part number, only the component parts from within it’s BoM can be received to stock.

As Vision is now assuming you are purchasing the phantom part (TPA-1) with all 5 component parts from within it’s BoM (TC-1 to TC-5) it has correctly stated in the MRP results that you only need to buy 100x of the phantom part and no other.

In the scenario below I have removed the tick from the ‘For suppliers of the part MRP will order PO kits’ checkbox (see second image below).

As you can now see in the first image below, the MRP results are now asking for all components required for the job and the Phantom part number is no longer mentioned.

You can search through the scratchpads to see if anything has the tick in the ‘For suppliers of the part MRP will order PO kits’ checkbox by dragging PTMPOKL into the Scratchpads User settings (see red arrow).

Anything with a ‘YES’ in the list will denote that it is checked (see green arrow), and you can then remove them, as mentioned above.

MRP Work Order Recommendations

Reference Contents > MRP Planning, Processing and Results > MRP Work Order Recommendations

This window enables you to obtain a list of all MRP recommended Work Orders due to be placed up to a date that you can enter in the Select Options window that is presented when the window opens.

NOTE: This window is also used when you operate Process — Sales Orders — Create Supply Orders from Order function. In this case the window has a title of Create Work Orders from Sales Order and there is no date selection. Parts are populated from the Sales Order selected when they are of type M, or A when the part has a BoM. The WO Reference is constructed as SO-123456-999-CUS999 where 123456 is the SO number, 999 is the SO line number and CUS999 is the customer code. This code is checked against current and past work orders and the part requirement is ignored if the code already exists.

Following date entry, the system prepares a list of all Order and Shortage Order recommendations made by MRP processing that relate to Make type parts up to and including the date entered. Any recommendations that have been marked as implemented will be ignored.

To the left of part numbers on the list are a set of icons that indicate as follows:
B = Will indicate whether the part processed in a regular Work Order or a Backflushed WO.
K = Indicates whether you have chosen to Kit the order immediately.
L = Indicates whether the kit list should be printed on the WO document.
S = Indicates that the recommendation is a Shortage Order where the need for delivery does not leave the normal lead time (including any MRP Lead Time Offset) for the part.
P = Indicates whether the document will automatically print after it is created.

Some button and menu functions act on multiple list selections. To select multiple lines, use the mouse to click and drag, and the shift and command (Ctrl) modifier keys.

Many functions are available from the MRP Order Options Menu which is also available by right-clicking anywhere on the window.

Button	Action
Route…	Click to amend the route operations that will apply to the single selected Work Order. Unless amended, standard routes are applied to all work orders created. That is, operations marked as Alternative are omitted from the route. This button control opens the Work Order Operation List Maintenance window to permit changes to the operational route for the single selected WO. After amendment, if the Apply To WO button is not clicked, the selected WO will have the assembly’s standard route of operations. NOTE: Every time a Work Order is created on the system a copy of the operational Process Route is created and held against that specific Work Order. When the WO is cancelled or completed, the route is automatically deleted. Work History records the operational activity. At the time of creating the WO you can amend the standard route, that can contain alternate operations. Capacity Planning takes account of the stored WO-specific route. Shopfloor activity and Work History reflects the stored route rather than the design Process Route. When creating a WO you can even drop standard operations which have no alternates and add completely new operations specific to the particular WO. Once the WO has been created, it is independent of the design Process Route. There are some rules and restrictions that apply: Any change can be made to the operations of a WO before it has been saved to the database. If the WO has not been kitted or backflushed, changes can be made to the operations. If any outwork operation has been placed on a Purchase Order or RFQ, that operation cannot have it’s operation number or work centre changed while it is still subject to a PO or RFQ. If some of the WO has been received, or Shopfloor data collected for the final operation, the final operation number cannot be removed or changed, nor can a higher operation number be added to the WO route. However, the details of the final operation, including Work Centre, can be changed. If an assembly has a Process Route, you cannot eliminate all operations for a particular Work Order. At least one must remain.
Toggle Backflush	To mark the entries selected in the list to be Backflushed WOs. Those already marked will be un-marked.
Toggle Fully Kit Now	To mark the entries selected in the list to be Fully Kitted when created. Those already marked will be un-marked.
Toggle List Kit on WO	To mark the entries selected in the list to List kit on printed WO. Those already marked will be un-marked.
Toggle To Print	To mark the entries selected in the list to be Printed after creation. Those already marked will be un-marked.
MRP Order Options	This menu of option functions for the window is also available by right-clicking anywhere on the window. See MRP Order Options Menu topic for functional details.
Create, Kit and Print WOs	Having prepared the list with the correct information, use to create, kit and print Work Orders in one process.

CUSTOM CAPABILITY: There is an oCustom1 object method that can be used to customise values within the list after it has been built and before sorting. $MrpWoListPreSort( pWoList, pCreatedFromSO) can be used to, for example, populate the WO Reference for each proposed WO. The parameter pCreatedFromSO is true if the list was derived from a Sales Orders — Create Supply Orders from SO function, otherwise it is false.

CUSTOM CAPABILITY: You can run custom code after a work order is created. It is available in oCustom1.$AfterWoCreated().

MRP Fuzzy Pegging Analysis

Reference Contents > MRP Planning, Processing and Results > MRP Fuzzy Pegging Analysis

After selecting a part in the MRP Results Listing window, clicking on the Fuzzy Pegging button will open this window.

Fuzzy Pegging is a sort of MRP demand pegging. In conventional pegging the system records the source of all dependant demand for a part through multiple levels. This is an enormously intensive process to add to the MRP processing and would consume considerable database space. As an alternative, Fuzzy Pegging is a presumptive analysis of the demand items that are currently on the system that could be contributing to the demand on the part.

The system carries out a multi-level where used analysis on the selected part and identifies any demand for parent items in the where-used list.

The list interactively operates with the Parts ScratchPad and the Bill of Materials and Where-Used Listings window that can be opened from the Parts ScratchPad Options Menu menu. This window will interactively operate with the Results Listing window. I.E. If you click on a BoM listed part the system will attempt to list the MRP results for that part.

MRP Purchase Order Recommendations

Reference Contents > MRP Planning, Processing and Results > MRP Purchase Order Recommendations

This window enables you to obtain a list of all MRP recommended Purchase Orders due to be placed up to a date that you can enter in the Select Options window that is presented when the window opens.

On confirmation, the system will then build a list of all MRP recommendations for Buy and Outwork assembly part supply types which have MRP Shortage or Place Order actions. Any recommendations that have been marked as implemented will be ignored.

NOTE: This window is also used when you operate Process — Sales Orders — Create Supply Orders from Order function. In this case the window has a title of Create Purchase Orders from Sales Order and there is no date selection. Parts are populated from the Sales Order selected when they are of type B, O, or A when the part has no BoM. The PO Header Reference is constructed as SO-123456-999 where 123456 is the SO number and 999 is the SO line number. This code is checked against current and historic purchase orders and the part requirement is ignored if the code already exists.

To the left of part numbers on the list are a set of icons that indicate as follows:
R = Will indicate whether the part will be in a regular Purchase Order or a Request For Quotation document.
S = Indicates that the recommendation is a Shortage Order where the need for delivery does not leave the normal lead time (including any MRP Lead Time Offset) for the part.
O = Indicates that the part is an Outwork Assembly type part and the resulting Purchase Order will need parts kitted to it.
P = Indicates whether the document will automatically print after it is created.

The system automatically applies the Primary Supplier to parts and links the part to the primary supplier’s purchase part record, if one exists. On the left of the list are indicators to show which orders are Shortages and which you have marked for printing.

Some button and menu functions act on multiple list selections. To select multiple lines, use the mouse to click and drag, and the shift and command (Ctrl) modifier keys.

MRP Run Demand Selection and Options

Reference Contents > MRP Planning, Processing and Results > MRP Run Demand Selection and Options

See the MRP Menu topic for a discussion on how MRP works.

Notes To The System Manager

MRP Processing is not possible when the BoM Lowest Level Numbers automatically adjusted control is NOT checked in the “System Preferences…”. It can only be set by running Re-organise Bill of Material file in the “Advanced”, “Re-set Data Files” suite of functions.

Extensive use of computer RAM memory is used during an MRP run, to give maximum performance. The Calendar and multi-level demand is stored in memory while forecasting is processed. You should ensure you carry out MRP Processing with plenty of RAM.

The results of MRP Processing are contained in the MRP Results data file. The first operation of processing is to clear all previous results. Cleared records are not removed from the database, only marked as inactive records. Thus the results file can grow but never decline in size. You should review the alternatives in the Options tab pane.

MRP Run Options

Each time you run MRP Processing you can set different demand and other options. These choices are recorded in the text of the History Report. These details can be printed at the end of the MRP Results report and are displayed on the History tab pane. The Parameters, shown in the Parameters tab pane are stored on file and will be offered as default for the next MRP Run.

Demand options

MRP Processing can selectively include demand from Stock Re-Order Levels, Open Sales Orders, Sales Quotations, Production Plan active and inactive items. Normally, only Stock Re-Order Level, Sales Orders and Production plan active items would be checked.

Delay Start

A option is provided to delay the start of the MRP run. If a time is entered (later than the current time) the computer will be put into a holding condition until the entered time. You must use 24 hour clock time. The status bar at the bottom of the window will show the start time and a countdown. The countdown can be cancelled by clicking on the Cancel Timed Start button. This provides for running MRP out-of-hours unattended. MRP can be run in background while using other programs, although this is not recommended unless the computer has sufficient power for both MRP and whatever other applications are running simultaneously.

Print Results Report

The Print MRP results report when complete option will enable you to print an MRP Results report after processing is complete. The results report can be very long and it is often convenient to print it out-of-hours. The MRP Results Report Selection window will open for you to choose report options. Do not print the report at this stage, simply set the options you want and leave this window open to process the report automatically when the MRP run is complete. For further details see the MRP Results Report Selection topic.

Quit [Exit] when complete

The Exit Program when Processing Complete option is provided to terminate your program session after running MRP Processing. This is provided for security reasons. This prevents an unattended terminal, with a high security clearance, from being tampered with. It also releases the data file for backup purposes.

Ignore Bulk

The Ignore Bulk Issue parts in dependant demand option, if checked, will have MRP ignore Bulk issue components from dependant demand. If bulk issue items are extensively used in Bills of Material, checking this option will reduce the number of MRP Results records and speed the processing. Bulk Issue parts are often best handled on a Re-Order Level basis and therefore it is recommended that this option is only checked if you include Stock Re-Order Level as a demand option.

Update ABC Codes

If checked, an ABC parts analysis will be run on the results of MRP when processing is complete. This will update all Part records with an A, B, C, D or E coding. The percent break points for each code are set in the “System Manager” “Company Details…” function. A, B, C and D codes are given to all items with MRP direct or indirect demand. E code is given to all parts that have no demand identified by MRP. ABC analysis is carried out using Current This-Level Costs for each item. When the Update ABC codes for Parts to reflect MRP results checkbox is checked the ABC analysis and update will automatically take place after the MRP run. A report will be produced of the analysis. You will be prompted for the report’s destination at the start of the MRP run.

NOTE: You can run ABC Analysis without running MRP Processing. Un-check all Demand and other Option checkboxes and check only the Update ABC… option. ABC analysis will then be run based on the current set of MRP Results.

Ignore re-order levels

If this option is checked, for the purposes of the MRP analysis, all parts are assumed to have zero re-order level planning value. This is useful only when you want to see the ‘what-if’ consequences of the planning value. You will be effectively running your stocks down to minimum stock.

Ignore minimum stocks

If this option is checked, for the purposes of the MRP analysis, all parts are assumed to have zero minimum stock planning value. This is useful only when you want to see the ‘what-if’ consequences of the planning value. If both re-order levels and minimum stocks are ignored, you will be effectively running your stocks down to zero.

Ignore minimum order quantity

If this option is checked, for the purposes of the MRP analysis, all parts are assumed to have zero minimum order quantity planning value. This is useful only when you want to see the ‘what-if’ consequences of the planning value. You will be effectively buying and making only absolute requirements and not batching up.

Ignore lot sizes

If this option is checked, for the purposes of the MRP analysis, all parts are assumed to have zero lot sizes planning value. This is useful only when you want to see the ‘what-if’ consequences of the planning value. You will be ignoring lot size adjustments to batch sizes.

Treat Future Outwork as Work Orders

This option forces the system to treat any future outwork assembly orders as work orders. It is used to provide a what-if capacity analysis to fill in-house capacity before outsourcing is contemplated.

Do Not Consolidate into PO Kits

Normally MRP, as a post-process, will attempt to consolidate PO Kits from their components where a phantom type part has a purchase part record. Checking this option prevents that post-processing and leaves orders for the components un-consolidated into kit orders. For the full implications to MRP see the Treatment of Purchase Order Kits section in the MRP Menu topic.

Calendar extent and active days

MRP only processes demand that falls within the Make and Buy Calendar limits, which are shown on the Parameters pane. To process items of demand planned further in the future, the Calendar must be extended. The number of Active days ahead gives you an indication of the extent forecasting is possible.

Push Order thresholds

This is the number of calendar buy active days beyond which an order will be pushed by MRP processing. If, during MRP processing, an existing order delivery is found to be earlier than required, MRP will recommend that the order delivery is “Pushed” forward to the date it is needed. The threshold is provided to limit the number of push recommendations by saying that the order delivery should only be pushed if delivery is needed after the threshold number of days beyond it’s original delivery due date. Otherwise the order is left with no change recommendation. Buy threshold relates to Purchase Order recommendations, Make relates to Work Orders.

Cancel Order thresholds

This is the percent of an order quantity calculated by MRP processing to be excess to requirements before a cancel recommendation will be made. If, during MRP processing, an existing order quantity is found to be greater than required by more than the percentage entered here, MRP will recommend that some or all of the order quantity is cancelled. Regardless of this threshold, MRP will not recommend a partial cancel if the remaining order quantity would fall below the order quantity (adjusted for lot size) for the part. The threshold is provided to limit the number of partial order cancel recommendations by saying that the order cancellation should only be recommended if there is a sufficient proportion of the order in excess of requirements. Otherwise the order is left with no change recommendation. If the threshold is set to 100%, only whole orders will be cancelled. If set to 0%, all recommended reductions to order quantities will be reflected as cancel recommendations, where part order quantity and lot size is maintained. Buy threshold relates to Purchase Order recommendations, Make relates to Work Orders.

Lead Time offset (+ or -)

This is an optional number of days added to (or subtracted from) Buy or Make part lead times. In normal circumstances these values would be set to 0. However, it may be useful to set values for these offsets to, in effect, globally change lead times temporarily for the purposes of an MRP run. Lead times for parts are never calculated as less than 1 day. Very useful for what-if calculations.

MRP time-bucket size

If set to 1, MRP processing records analysis of forecast inventory movements to an accuracy of a single active buy or make calendar day. For a coarser analysis, with less detailed results, you can increase the time-bucket. Increasing the bucket size has no effect on inventory quantities. However, you must recognize that the time-bucket size effectively puts a floor on part lead times and as a result will tend to extend accumulated lead times for assemblies.

Part yield effects results

If this checkbox is checked, any non-100% yield rates or non-zero yield unit loss on parts will effect the way MRP will calculate order quantities and dependant demand. See the Part yield in lost units per batch rather than percent rate system preference for details.

MRP will use the Yield value to recommend ordering more (if less than 100% rate or more than zero units of loss) of the part than is subsequently received into inventory. For a purchased item this is straight forward. For an item with a BoM, the ordered quantity of components will be assumed to be consumed.

WARNING: Care should be taken in the use of Yield rates or high loss units as they can accumulate excess quantities rapidly, especially where multiple sub-assemblies contain yield rates.

Run MRP

The system keeps a record of the last MRP Run, and the details are shown in the History tab pane. The start date and time and finish time and duration of processing are recorded. In addition, the demand selection criteria and other statistics are maintained. During the run the statistics of processing are shown in the Alert Message window.

If any demand item is found to be beyond the extent of the Calendar, it will be listed with an appropriate reference to a Plan item, Sales Order, Job, Purchase Order or Work Order.

On completion the predicted change in Stock Value is shown along with additional results statistics.

TIP: MRP processing requires numerous recursive list manipulations and if data is corrupt or damaged the process can hang. There is therefore a limit set for the number of recursive loops that can be performed. This defaults to 100. The option optMRPLoopMax allows you to control this in debugging situations. Set to 10 or greater, otherwise the default will apply.

WARNING: Due to a system limitation, the current computer date and time are those accessible in the terminal’s “Control Panel”, not the File Server’s. It is important, therefore, for correct data integrity, that all terminals in a multi-user network have their time and date synchronised.

CUSTOM CAPABILITY: The oCustom1.$MrpRunStart() method provides a custom method that would enable variables to be set up in advance of MRP Processing (but not for ABC Analysis only) that can be used in a custom post-MRP-processing feature. This can be developed in OpenVision Customisation.

CUSTOM CAPABILITY: The oCustom1.$PostMrpProcessing() method provides a custom method that will be run after MRP Processing and ABC Analysis but before any Results Report has been printed. With this you can program any post-MRP processing you wish. This can be developed in OpenVision Customisation.

The window has 4 tab panes.

Print Parts ABC Analysis	Check this option to print an ABC Analysis after processing.	User Settings
Report destination	Set the report destination for the ABC analysis.	User Settings
Report file path	This is the path of the print file, where appropriate. Use the Set File button to set and change it.	User Settings
Set File	If the destination you have set is a file, use this button to set the file path.
Ignore Re-order Levels	For the purposes of MRP processing re-order levels for all parts will be assumed to be zero.	Not Saved
Ignore Minimum Stocks	For the purposes of MRP processing minimum stock quantities for all parts will be assumed to be zero.	Not Saved
Ignore Minimum Order Quantities	For the purposes of MRP processing minimum order quantities for all parts will be assumed to be zero.	Not Saved
Ignore Lot Sizes	For the purposes of MRP processing lot sizes for all parts will be assumed to be zero.	Not Saved
Treat future Outwork as Work Orders	Check this to treat any future outwork assembly orders as work orders. Used to provide what-if capacity analysis to fill in-house capacity before outsourcing.	Not Saved
Do Not Consolidate into PO Kits	Normally MRP, as a post-process, will attempt to consolidate PO Kits from their components where a phantom type part has a purchase part record. Checking this option prevents that post-processing and leaves orders for the components un-consolidated into kit orders. For the full implications to MRP see the Treatment of Purchase Order Kits section in the MRP Menu topic.	Not Saved
	Delete Old Record Options
Delete File Slot (if single-user)	Deletes the entire MRPFILE slot, but only when run in single user mode.	Not Saved
Clear Old Records	The records are only marked by having the part number removed. The number of records is the result file will not reduce using this technique, but it may be faster.	Not Saved
Delete Old Records	The records individually deleted. This clears the datafile and can be done when others are attached to the datafile, but it may well be slower.	Not Saved
	Other Options
Use Serialisable Transactions	If checked, the program will save result batches within serializable transactions. As MRP Processing reads and saves MRP Results, it does a lot of disk work. It does this in batches as it deals with part after part. Under some circumstances encapsulating these batch updates or inserts into single transactions can speed the process up. Rather than 10 inserts individually, it does a block of 10 in one go. This can be faster, but not necessarily. Sometimes the overhead of a serialisable transaction outweighs the processing gain. It all depends on the data distribution. Hence this option. On some sites it won’t help, on others it may improve performance significantly. When you choose Use Serialisable Transactions you get a (ST) after the processing time on the Alert Message.	Not Saved
